I Need Help And Information

I need some help and information from folks familiar with Social Security and Medicare. I have an adult cousin who is on Social Security for very difficult mental health issues/bipolar disorder. He has been on Social Security Disability for a long time as the survivor/disabled child of a Social Security Payor. He has been able to live pretty well on Disability.

So his Father and Mother are both deceased. He gets a pretty good monthly disability check as a Disabled Survivor Child based on his Father's account. Anyway, the family and I are worried about his benefits and medical insurance being cut by the incoming Trump Administration. He also has Medicare which pays for his treatments and his very necessary psychiatric drugs.

I worry about his future as he has no way to survive without Social Security and Medicare. There is no immediate family who can afford to take him in and care for him. So what do you think here? Is my fear of his Social Security being cut real, or is it unlikely? I wouldn't put anything Trump and his gang. Thanks in advance for any responses.
